Floodwaters receded Saturday from much of the tourist town of Talkeetna, giving residents a chance to begin cleaning the muddy mess left behind — but officials warned that the danger hadn't passed and advised that people boil their water.

About 200 miles south, in Cooper Landing on the Kenai Peninsula, the Kenai River had yet to crest and the National Weather Service extended a flood warning until Monday afternoon saying that the river will continue rising. Residents of one subdivision were told to be ready to evacuate.

Forecasters said rain would continue falling Sunday, making it tough to predict how high waterways would rise on the peninsula and when they'll crest.

The outlook seemed a bit better in Talkeetna. Rivers and streams draining from the Talkeetna Mountains had crested and water levels fell steadily Friday night, the weather service said. Meteorologists said they don't expect rainfall to significantly increase river levels there, but a flood warning remained in effect for the area as many waterways remained above flood stage.
